Engine rear support



Patented Sept. 15, 1931 iITl-:D STATES PATENT OFFICE BENJAMIN H. ANIBAL, F PONTIAC, MICHIGAN, ASSIGNOR TO GENERAL MOTORS COR- PORATION, OF DETROIT, MICHIGAN, A CORPORATION OF DELAWARE ENGINE REAR SUPPORT Application led July 27, 1927. Serial No. 208,887.

This invention relates to a cushioned supporting means.

It is an object of this invention to provide a cushioned connection between two parts of an automotive vehicle, such as between the supporting arm ot the engine and the Jframe. Another object is to provide a simple connection ot this type which is strong and durable and which entirely 1'). eliminates metallic contact between the engine and trames thus avoiding the transmis,

sion of vibration v'from the engine to the frame.

Other objects of the invention will appear 5 in the course of the following description, taken in connection with the accompanying drawings and appended claims.

In the drawings- Figure 1 is a view, mainly in cross section, Z'j showingmy supporting means arranged between the engine and frame of an automotive vehicle.

Figure 2 is a plan view of the construction shown in Figure 1. y,

Figure 3 is a side elevation of the construction shown in Figures 1 and 2.

Referring to the drawings7 the numeral 10 indicates the frame of an automotive Ve hicle and the numeral 12 the rear corner` of fda the engine. Rigidly connected to the engine by means ot the bolt 14 is the connecting arm 16. This arm is U-shaped in section as shown in Fig. 1 and is provided with side tianges 17. ltigidly fixed within the chan- 55 nel-shaped frame member 10 by means of rivets 2O is the supporting bracket indicated generally at 22. bracket is formed of a single piece of sheet metal, bent to forma base 21 with two side 10 portions QS each ot which is provided with a bent out part 2) for riveting to the web of the frame, and two inwardly turned upper portions BO riveted to the upper flange ot' the trame 10.

Between the bracket 22 and arm 16 of the engine is the L-shaped strip 3i ot cushioning material7 such as rubber. The arm 16 is connected to the 'trame 1() by means of bolts 36 and 25h. The apertures in the horizontal portion 2l ot the bracket and the web of This supporting' the frame are ust large enough to tit snugly over the respective bolts 36 and 38. The corresponding apertures 4() and 42 in the horizontal and vertical flanges ot'the arm 16.` however, are sutliciently larger than their respective bolts to allow a limited amount of movement of the arm 16 with respect to the trame. Surrounding the boltsv 36 and 38 are the thick cushioning washers 41 ot material similar to that of the cushion 31 and fitting over each washer 4l is a cup-shaped metallic washer 16. Some clearance is provided be- A tween the surface of the arm 16 and the rim of each metallic washer 46 to allow for a small amount of vertical and lateral Inovement.

I thus provide an entirely non-metallic connection between the engine supporting arm and the frame. It will be understood that the connection between each side of the engine and its respective frame member is the same. The connection described in detail in the present case is one of the rear connections ot a three-point suspension, any suitable connection for the front end of the engine being used.

I claim:

1. In combination with a supporting member having a pair of angularly related surfaces, a member supported by said supporting member and provided with surfaces adjacent the surfaces of the supporting member and substantially parallel there# to, an L-shaped strip ot cushioning material having a leg positioned between each pair of parallel surfaces and in continuous contact with the pairs of angularly related surfaces, aligned openings extending through each pair of parallel surfaces, and securing means of smaller diameter than the opening through one of each pair of parallel surfaces extending through each pair of aligned openings.

2. In combination with a supporting member having a pair of angularly related surfaces, a member supported b v said supporting member and provided with surfaces adjacent the surfaces ot the supporting member and substantially parallel thereto, an L-shaped strip of cushioning material having ay legpositioned/,between each pair of parallel surfaces andiny continuous contact with the pairs of angularly related surfaces, aligned openings extending through :eachpairof parallel surfaces, headed securing means of smaller diameter than the l"opening through one of each pair of parallel surfaces extending through each pair of alignedopenings, and Acushioning means between the head of each securing means and the surface of the adjacent member.

3. In combination, a channel-shaped supporting member, a channel-shaped bracket secured to the flanges and web of said supporting member, a member supported by lSaid supporting member and includinga portion extending into the channel of said i bracket and the channel of said supporting vmember, and cushioningA means between said portion and the web of the supporting member and between said. portion and the web y of the bracket. v I

4. The inventionv claimed rin claim 3- in which the cushioning means is in the form of an Lshaped strip;

5. In combination, a channel-shaped supporting member. a channel-shaped bracket,

secured to the flanges and web of said supporting member. a member supported by said supporting member. a channel-shaped bracket extending into the channel of the first-mentioned ,bracket and having a flange vsecured to said supported member, cushionj second-mentioned bracketand web of the .second-mentioned bracket,

supporting member and between the web of the second-mentioned bracket and the web of the first-mentioned bracket, aligned openings extending through the web of the supporting member and the adjacent flange of the second-mentioned bracket, aligned openings extending through the web of the first-mentioned bracket and the web of the and securing meansof smaller diameter than one of each pair of aligned openings extending through each pair of openings.

7. The invention claimed in claim 6 in which each of said securing means is provided with a head ont-one end thereof, and

cushioning means under the head of eachof the securing means.

l8. A mountingof the class described`v com.- prising, a channel shaped framevmember, an internal j combustion engine having' an outwardlyfextending arm, means for forming a connection between said arm andnsaid frame member, `and a resilient-pad incontinuous contact with two' adjacent sides of said frameV member, between said frame member and said arm.

In testimony whereof I afiix my signature.

BENJAMIN ANIBAL.
